Facing the differences in the literature concerning the ways uncertainty, imprecision, ambiguity, indetermination ..., are denominated, we adopted the more general designation of imperfections of the information. The imperfections have various sources and kinds. In the decisional context, particularly in any multiple criteria decision aid process, the presence of the imperfections is unavoidable. It is then obvious to seek for additional information in order to reduce these imperfections. The question is then : how to deal with the additional information? The proposed procedure allows processing the additional information in a multiple criteria decision context affected by different kinds of imperfections of the information. This unified procedure is based on the Bayesian model and the adaptation of information revision rules from the uniattribute context to the multiattribute context.
